以下HTML和CSS
.container {
position: relative;
border: solid 1px red;
height: 256px;
width: 256px;
overflow: auto;
}
.full-height {
position: absolute;
top: 0;
left: 0;
right: 128px;
bottom: 0;
background: blue;
}<div class="container">
<div class="full-height">
</div>
</div>内部根据div需要占据容器的整个头部.如果我现在向容器中添加其他一些流内容,例如:
.container {
position: relative;
border: solid 1px red;
height: 256px;
width: 256px;
overflow: auto;
}
.full-height {
position: absolute;
top: 0;
left: 0;
right: 128px;
bottom: 0;
background: blue;
}<div class="container">
<div class="full-height">
</div>

</div>然后容器根据需要滚动,但绝对定位的元素不再锚定到容器的底部,而是停在容器的初始可视底部.我的问题是; 有没有办法让绝对定位元素成为其容器的完整卷轴高度而不使用JS？

您需要将文本包装在div元素中并在其中包含绝对定位的元素.
<div class="container">
<div class="inner">
<div class="full-height"></div>
[Your text here]
</div>
</div>
CSS:
.inner: { position: relative; height: auto; }
.full-height: { height: 100%; }
设置内部div的位置relative使其内部的绝对位置元素基于它的位置和高度而不是.container具有固定高度的div.没有内部,相对定位div,.full-heightdiv将始终根据其计算其尺寸和位置.container.

position: fixed;将解决您的问题.例如,检查我的固定消息区域覆盖的实现(以编程方式填充):
#mess {
position: fixed;
background-color: black;
top: 20px;
right: 50px;
height: 10px;
width: 600px;
z-index: 1000;
}
并在HTML中
<body>
<div id="mess"></div>
<div id="data">
Much content goes here.
</div>
</body>
当#data变得更长时,#mess保持其在屏幕上的位置,同时#data在其下滚动.
所以gaiour是对的,但是如果你正在寻找一个不与内容一起滚动的全高度项目,但实际上是容器的高度,这就是修复.拥有导致溢出的高度的父级,具有100%高度的内容容器,overflow: scroll然后可以根据父级大小而不是滚动元素大小来定位兄弟.这是小提琴:http://jsfiddle.net/M5cTN/196/
